Specification of ietters Patent. y Patented May 20,

Application inea July s', 191s, serial No. 243.2526.

To all 'whom it may concern:

' Be it known that I, ALBERT EDWARD HORN- BY, a subject of the King of England, residing at Rhyl, North Wales, Great Britain, have invented certain new and useful Improvements in and Relating to Flushing Apparatus for Water-Closets and the like, of which the following is a specification.

My invention relates to liushing apparatus for water closets and the like, and tothe type of apparatus in which `a closed-inves'- sel or reservoir, capable of being sealed, receives the flushing water, said closed-ln ve'ssel being provided at the top with a float valve which opens to air when emptying and is closed by the incoming water when the same reaches the top or thereabout of the vessel, compressing the air therein, so that on the flushing valve being opened the first flow of water takes place under coni'- pressed air till the seal of the vessel is broken y the float valve opening to atmosphere after which the flush is byV gravity.

The present invention has for its object the improved combination, construction, arrangement and working parts constituting the apparatus as herein described and shown in the drawings. In the latter l:-- Y

Figure 1 is an elevation, partly in section, of the apparatus; Y Y

Fig. 2 is a plan view, partlyI in section, and drawn to a larger sca-le, of the ushing valve and operating means therefor;

, Fig. 3 is a sectional elevation, drawn to a larger scale, of the air chamber of the apparatu's;

Fig. 4 is an end view, also drawn to a larger scale, of the means for actuating the water 'supply tap ;Y and Fig. 5 shows some details, partly in sec- Similar parts are designated by' like references throughout the several views. Y

In carrying out my' iiive'nticff I make pro` vision of a closed-in vessel or cistern a with water connections d, c' at its lower end, Fig. 1, and to one of these connections -the other .being cappedis attached the branch pipe c1, Fig. 4, leading from the water supply tap c2. To the top of the cistern a there is attached an air-chamber I), Figs. l and 3, the same having therein a float valve y' and valve seating jl, and c is the air inlet pipe to said chamber To the upwardly dished bottom 7c of the cistern a there is connected the flushing chamber or valve b1 which is. divided into two parts by a partition t in which is formed the valve seating h1. The valve disk d and integral valve, sho'vvn qin Fig. 1 in lclosed position and in F ig. 2 in open position, are carried by a v'alve rod 'or spindle d'1 which passes through Va stuffing box and regulating mit g arranged iii the flushing 'chamber b1. The spindle d1 is provided Vwith t. ferrea and eletted enter guide erid '12,

and above 4said slots passes the pivot 'pin f1 of the actuating handle f, the ends or said pivot pin f1 being adapted to take the ends of the extensions or brackets b2 frning integral parts of a nut or easing which is screwed ont a branch y of the ushing chamber b1, Fig. 2. The handle f is moreover provided with a `chain Z by means of which it een be pulled down' when in the-po- 'siticiij indicated in Figs. 2 4. e is a coiled spring encircling the valve rod or spindle d1, one end of said spring bearing against the tutg' mi the other end against the forked end d2 ofthe spindle. The compressin of the "spring can thus be regulated by means o-f the nut g. Y

On one of the laterally prjecting ends of the pivet p-in f1 is mounted a counter balancing` weight al, Figs. 2 and 4, in su'ch a manner as te tend to keep the handle f noiinally in an upright po'sitin' and thereby holding the valve d open. The handlein relation to its' upright position-es formed at its lower' end with an integral eitension in the shape of aforked boss adaptedto receive a roller f2 so that upon' the handle being pulled down the roller f2 is brought to bear against the inner end of the forked member of the spindle d1 thereby comp-ressing the spring e' andeasing the valve d to close, Fig. l. i

On the other prejecting end of the pin f1 is slidably mountedva socket piece c2 which germany ie engagement with the plug g1 of the water supply tap c2, but, when required, can be disengaged from said plug as shown in Fig. 4. Y

In action, water from the towns supply, constant and under pressure, enters the cistern a by way of the tap c2, branch c1, and union or connection z', rising in the cistern, driving out the air therein, which air passes Athe float valve j in the chamber b, Fig. 3,

and escapes by way of pipe c. On the water reaching said oat valve j, the latter is lifted on to its seating jl, sealing, and maintaining sealed by the constant pressure of Water, the vessel or cistern a.

When a flush is required, the handle f is pulled doWn which movement causes a corresponding rotary movement of the pivot pin f1 and the socket piece e2 Which in turn, actuates the plug g1 of the tap c2 thereby opening the Water supply and permitting a certain quantity or charge of the cistern, say three gallons, being used at the time of flushinfr.

'.Ihis downward movement of the handle f also brings into action the roller f2 and causes the shutting of the valve CZ in the manner hereiirbefore described, the doWn- Wardymovement being arrested by pins or rollers e1 suitably mounted in the extensions of the bracket b2 and the slotted portion of the fork (Z2 respectively. Upon the release of the handle f the latter, by the action of the counter balancing Weight a1 and the spring e, returns to its normal position, Figs. 2 and 4, the valve CZ thus being Withdrawn from its conical seat 71,1 and allowing the water to flow through the flushing chamber b1 and outlet pipe b3 in order finally to pass to the pan or the like'to be flushed.

At the same time the seal of the chamber b is broken, the iioat disk j dropping from o its seat jl in said chamber, thus permitting of the ingress of air to the vessel or cistern a. l/Vhenever a flush is required, the same process is repeated; that is, the handle j is pulled down and, after a certain time, released.

In order to prevent corrosion or foreign matter to pass into the cistern a, I prefer to employ a perforated Zinc screen or filter K, F ig. 5, the said iilter being mounted inra three-Way branch pipe of which the branch l L is connected with the inlet tap c2, While the branch L1 is designed to be connected to the town supplyl pipe. The third branch M is ordinarily closed by means of a screw plug N adapted to be disconnected to permit the filter to be taken out for cleaning purposes.

Having now fully described my said invention what I claim and desire to secure by Letters Patent is 1 l. In the herein described flushing apparatus, the combination, With a cistern and Water inlet and air outlet connections provided thereon, of a two-part flushing chamber arranged at the bottom of the said cis- -tern and communicating with same, a bracket casing attached to the flushing chamber and having slotted extensions, a slidable and spring-controlled valve spindle mounted Within the bracket casing, a disk valve secured to the inner end of said spindle and projecting into the flushing chamber and opposite a conical valve seat provided in the partition of said chamber, means to regulate the compression of the spring of the valve spindle, and means to control in unison the Water inlet and the flushing valve, all substantially as set forth and for the purpose shown.

2. In the herein described flushing apparatus, the combination, with a cistern and Water inlet and air outlet connections, of a two-part flushing chamber arranged at the bottom of the cistern and communicating with same, a conical valve seat formed in the partition Wall of said chamber, a bracket attached to the latter and having slotted eX- tensions, a slidable spring-controlled valve 4spindle mounted Within the body of the said bracket, a disk valve secured to the inner end of the spindle, and means vto simultaneously actuate the valve and the Water supply, said means comprising a forked eXtension provided at the outer end of the valve spindle, a handle pivotally mounted in the extensions of the aforesaid bracket and having a downwardly projecting boss, a roller journaled thereinA and adapted to be brought to bear against the forked extension of the valve spindle, and a pin forming the pivot of the handle, one end of said pin carrying a counter balancing Weight and the other end connecting with and operating the tap of the Water supply, all as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
